I'd have to not agree, have 2 extremely productive spitter upers. I kinda get tired of some moms (mainly referring to relatives and a certain friend) who over dramatize something that I think is pretty normal in babies the first year of life and complain about how many times that day their baby had vomited when really they are just spitting up. (Not saying that anyone here is being dramatic at all
) My kids would spit up all the time and it would be a lot, and often multiple spit up was common. Till one day one of them actually vomited and boy could you tell the difference. It was extremely forceful, projectile, and looked much more digested than any spit up I'd ever seen. Oh and he only vomited once, so I don't think you can count how many times to define it.
